Wills are an essential part of estate planning, leaving instructions for how to distribute your assets and possessions after you die. Trusts are a common tool in estate planning as well, serving as a way to manage assets both before and after your death. If your will conflicts with a trust that you have set up, the trust will typically prevail. This is because, in most cases, the assets in a trust don’t technically belong to your estate any longer. They are legally owned by the trust itself, so the terms of your will don’t affect them. This doesn’t mean trusts are always the better option. There are a number of factors you need to consider before making a decision.
A financial advisor can provide insight on different estate planning strategies to help you find the one that matches your goals and legacy wishes.
The Definition of a Will
A will is a legal document that outlines a person’s wishes regarding the distribution of their assets and the care of any minor children after their death. It allows the testator (the person creating the will) to name beneficiaries, appoint an executor to manage the estate and specify guardians for dependents. A will only takes effect upon the testator’s death and must go through probate, a legal process to validate and execute its terms. Among other issues, a will establishes:
- Who will take possession of your cash, investments, belongings and other property
- How to pay any remaining debts or obligations
- Any long-term or ongoing plans that you would like to make
- The care and distribution of any real estate you own
How a Will Works
Wills are an essential part of estate planning. When you die, everything that you own is collectively known as your estate, which then gets distributed among your heirs.
If you leave a will, your estate is distributed according to your wishes and that process is overseen by someone you select, known as the executor. If you die without a will, known as dying intestate, your estate is distributed according to the inheritance law of your jurisdiction. That process is overseen by someone appointed by the probate court, known as an administrator.
Under typical circumstances, a will is managed through and by probate courts. Your executor will file your will with the court which in turn oversees the entire process of settling your affairs and distributing the estate’s assets. For most estates, the probate process is largely a formality. The court makes sure that your will is legal, that your estate pays its debts and that your executor has the access they need to distribute your assets.
The same process occurs if you die without a will. In that case, the probate court appoints an administrator. The court then ensures that the administrator distributes your assets according to the local inheritance laws.
The Definition of a Trust
A trust is a legal arrangement in which a person (the grantor or settlor) transfers assets to a trustee to manage and distribute them for the benefit of one or more beneficiaries. Trusts can be revocable (allowing modifications during the grantor’s lifetime) or irrevocable (generally permanent and unchangeable once established). Unlike a will, a trust can help avoid probate, provide greater control over asset distribution, and offer potential tax benefits and asset protection.
Every trust has four main components, which are:
- Contributor: The person who created the trust and contributed assets to it
- Assets: The cash, property and other assets owned by the trust
- Trustee: The individual or firm that manages the trust’s assets
- Beneficiary: The person or persons who receive assets from the trust
How a Trust Works
When you create a trust, you put assets in its name. Once you do that the assets belong to the trust itself, not you. This is the same as with any other property transfer. The trust is a legal entity capable of owning assets, paying taxes and making distributions. So once you put something in its name that property legally belongs to the trust itself, not you.
In creating a trust, you also establish its terms. You name the trustees and the beneficiaries, and set out the terms for how the trustees should manage the trust and its assets. This includes instructions for what assets the beneficiaries will receive, along with how and when. For instance, you can leave instructions for your trustee to distribute your funds equally among your children after you die.
Can a Will Override a Trust?
There are two main circumstances in which a will can conflict with a trust.
First, a will might give instructions that conflict with the terms of a trust that already exists. For example, your will might include language that leaves the family home to your children, while earlier in life you placed that house in a trust for tax purposes.
Second, a will might give instructions that conflict with the terms of a trust that doesn’t exist yet, or which hasn’t yet received its assets. For example, your will might include language that distributes your investments among your children. Meanwhile, another section of the will might include language that places your investments in a family trust.
When the Will Does and Does Not Have Authority
In the first case, the terms of the will have no authority. A will cannot override a trust that already exists, nor can it distribute or manage property already held in an existing trust. If a trust exists and holds its assets, those assets belong to the trust itself. They are not part of your estate and, as a result, are not subject to the terms of your will.
If your will gives instructions that conflict with the terms of a trust, your will’s terms will apply to the assets in your estate and the trust’s instructions will apply to the assets in the trust. The designated beneficiaries will receive their assets according to the terms of the trust.
In the second case, your will does not conflict with any existing trust. Instead, it is internally contradictory and will be resolved according to local inheritance law. You can leave instructions in your will to put assets in trust. This can apply to a trust that already exists, where your will puts assets into a trust that you created earlier. It can also apply to a testamentary trust, where your will instruct the executor to create a new trust and put assets into it.
Settling the Estate
In both cases, these assets belong to your estate when you die. This means that the terms of your will govern how those assets are distributed. If one section of your will conflicts with the section of your will that creates or contributes to the trust, then the issue is that your will is internally contradictory. The trust itself is not in question, just the will.
In that case, the probate court and your executor will have to determine the exact nature of the internal conflict in your will. They will then resolve that conflict according to state and local inheritance laws.
Your will still cannot supersede how an existing trust manages its assets. But conflicts in your will can prevent new assets from being added to the trust. This is why, if you plan on making or managing a trust, it’s wise to have a lawyer help you write these documents.
When Should You Use a Will vs. a Trust?

Wills and trusts are, generally, the two most significant vehicles for estate planning. Broadly speaking, if you’re looking to leave assets to your heirs, you will likely use one or both of these. While a full exploration of the subject is beyond the scope of this article, there are some good rules for when you should use a will versus a trust.
Wills and trusts are not mutually exclusive; their control over specific property is. Any given asset can either be put in trust or distributed by a will – but not both. However, you can manage your estate in general by putting some assets into a trust and distributing others through a will.
Wills: Good for Mid-Sized Estates, Simple Transfers and Instructions
In general, wills have the benefit of simplicity. While wills do not have the tax and probate benefits of a trust, the truth is that these concerns are frequently overstated. The federal estate tax only applies to large estates, beginning at $13.99 million in 2025. The probate process can take some time. However, it typically is only lengthy and complex for particularly large or contentious estates. If you have an ordinary scope of assets, the odds are good that neither taxes nor probate will be a burden for your heirs.
Yet, at the same time, wills are one-shot instruments. This makes it good for making simple distributions and leaving direct instructions. But once the terms of the will have been carried out, the estate is closed.
The result is that wills are often a good choice when you want to leave someone an asset in its entirety, such as leaving an amount of cash or a home to one single heir. They are also good for small and mid-sized estates, as a trust would impose additional costs and complications to solve tax and probate issues that these estates likely will not have. Finally, wills are good for leaving instructions beyond the scope of assets, such as arranging for the care of minor children and pets.
Trusts: Good for Larger Estates, Ongoing Wishes and Contestation
In general, trusts have the benefit of third-party management. When you put money into a trust you legally hand it over to a third party. This creates costs and complications that a will does not have. The trust will require instructions and terms, and you will need to pay for a trustee to oversee the trust’s assets.
This same process, however, means that your estate moves out of your name. You can do this before death, through a living trust, after death, through a testamentary trust, or in totality, through what is known as a pour-over will. This last is a will that bequeaths all of your property to a trust. So there’s no risk of accidentally leaving any assets to the probate process.
Moving assets out of your name makes trusts good for estates that are large enough to trigger tax and probate concerns, such as if your estate is worth more than $14 million at the time of writing. They’re also good for people who want to leave ongoing instructions after they die. For example, maybe you’d like to ensure that a piece of property remains in the family without being sold.
Finally, trusts are good for people who anticipate contested issues, as the trust will avoid the probate process that opens the door for heirs and debtors to challenge the estate.
Deciding Between a Will or a Trust
When you’re trying to decide whether to leave assets in a will or a trust, a good rule of thumb is this: Wills are a good choice when you have a simple transfer to make. If you want to leave someone money or property to own outright, and you aren’t a multimillionaire, a will might be your best option. Trusts are a good choice when you have a large or complex issue of inheritance.
If your estate is worth several million dollars, or you want to ensure that your assets are transferred and managed in a specific way, a trust may be your best option.
How to Coordinate Wills and Trusts in an Estate Plan
Coordinating wills and trusts in an estate plan helps avoid confusion, duplication, and costly mistakes when transferring wealth. A will directs how assets in your name are distributed after death, while a trust can manage assets during your lifetime and beyond. Because these documents work differently, they must be drafted to complement one another. Overlaps or conflicting terms can create legal complications, delay administration, or even result in unintended distributions. A well-structured estate plan uses both tools to cover every asset and clarify who manages what, reducing uncertainty for heirs and executors.
In many estate plans, the trust serves as the central management vehicle, while the will acts as a supporting document. Assets placed into a revocable living trust during your lifetime are governed by the terms of that trust, avoiding probate and allowing for private administration. Meanwhile, the will can handle property that was not transferred to the trust, appoint guardians for dependents, and provide final instructions for debts, taxes, or personal items. When the two documents align, they work together to create a seamless transfer of assets that reflects your wishes.
A pour-over will is often used to bridge any gap between a will and a trust. This type of will directs that any remaining assets owned personally at the time of death be transferred into the trust.
For example, say you acquire property late in life and forget to retitle it in the name of your trust. The pour-over provision allows it to be incorporated into the trust after probate. This keeps your estate consolidated and managed under one consistent set of terms, preventing assets from being overlooked or distributed outside your intended plan.
What to Consider
To coordinate wills and trusts effectively, all beneficiary designations, property titles, and account registrations should be reviewed regularly. Assets like retirement accounts, life insurance, and brokerage accounts often pass directly to named beneficiaries, outside both the will and the trust. If those designations do not align with your broader plan, conflicts can arise. Periodic reviews, especially after major life changes such as marriage, divorce, or inheritance, can help maintain consistency across all estate planning documents.
Creating a coordinated plan requires balancing control, privacy and simplicity. A will offers flexibility for personal matters, while a trust provides long-term structure and privacy. Together, they form the foundation of a comprehensive estate plan that protects your wishes and minimizes the burden on your family. Keeping your estate plan documents consistent and up to date helps preserve the integrity of your plan, reduce administrative delays, and limit the risk of disputes after your death.
Bottom Line

A will cannot override the terms of an existing trust. Once assets are transferred into a trust, they are no longer considered part of your estate. This means your will has no legal authority over them. This distinction is crucial for estate planning, as any attempt to distribute trust assets through a will would be ineffective. However, complications can arise if a will includes provisions to transfer assets into a trust, particularly if there are conflicting terms that prevent the transfer. To ensure your estate plan functions as intended, it is essential to carefully coordinate your will and trust, avoiding inconsistencies that could disrupt asset distribution.
