One of the most important things you can do when you start making an estate plan is to pick the right trust structure. Testamentary trusts and living trusts are both good ways to pass on money and protect beneficiaries, but they work very differently when it comes to timing, control, privacy, and what happens after you die. 

While you are still alive, you create and fund a living trust, which is also called an inter vivos trust. It starts working right away and lets the assets in it skip the probate process. A testamentary trust, on the other hand, is set up in your will and doesn't start working until after you die. Before it can be used, it has to go through probate. Knowing what features are most important to you will help you choose the right structure for your needs. 

What Is a Testamentary Trust? 

A testamentary trust is created through your last will and testament. While you're alive, it doesn't exist as a separate legal entity. It only comes into being after you die, when your will has been accepted for probate, and a court has confirmed it.  

Because it's made through the probate process, the trust becomes part of the public record. Anyone can read your will and see how your assets will be divided and who will get them. Once the court approves everything, a trustee takes over managing and distributing your assets according to your wishes. This process can be costly both in time and money. But for larger estates, an irrevocable trust can also help reduce estate taxes. 

People often use testamentary trusts when they want to make staged distributions over time. For instance, they may want to give a child portions of their inheritance when they reach certain ages or milestones, or hold assets for a minor who can't legally manage property. In blended families, they're also used to balance the needs of a surviving spouse with those of children from a previous relationship.

What Is a Living Trust? 

As the name implies, in a living trust, you act as your own trustee during your lifetime, which means you have full control over the trust's assets. You also choose a new trustee who will take over when you die or can no longer manage the trust.  There are two main kinds of living trusts: revocable and irrevocable. In a revocable trust, you can change the rules, add or take away assets, or even end the trust. The most important practical benefit of a revocable living trust is that it lets you avoid probate. If you die, the trust's assets go directly to your heirs without going through the courts. Additionally, a living trust allows your successor trustee to take over without the need for a court order if you become incapacitated.  Once you set up an irrevocable trust, you usually can't change it without the court's permission or the beneficiaries' permission. The trade-off is that you are giving up control in exchange for better asset protection and some tax benefits.

Key Differences Between Testamentary and Living Trusts

There are three primary distinctions between a living trust vs. a testamentary trust: how much control you have during your lifetime, when they are established and funded, and what happens to your privacy. Our guide to trusts goes into more detail about less common trust structures. 

  • Funding and timing. As soon as a living trust is established and funded, it begins to function. A testamentary trust requires no action while you're still alive, but it doesn't take effect until your estate goes through probate. 
  • Authority over life. A revocable living trust is under your control. You are free to handle your assets as you see fit. A testamentary trust does not yet exist. Until you pass away, your property remains in your name.
  • Management and privacy. Living trust documents are not in the public domain. A testamentary trust is public and subject to the probate process since it is created by a will. That makes a significant difference for families who wish to keep the specifics of their estate private, such as who gets what and how much. 

Probate and Administration Implications 

Courts use probate to verify the validity of a will, settle debts, and oversee the proper distribution of assets. For testamentary trusts, there is no way to avoid it. Depending on your location and the complexity of your affairs, that process may take several months. For beneficiaries who depend on that money, waiting can be financially and emotionally difficult. Additionally, the estate's value may fluctuate in market value or simply decline due to the various legal fees of the probate process. 

Living trusts do not share those risks of a long, drawn-out distribution process. Your successor trustee can begin working immediately after your death. There's no need to wait for a judge to approve anything. The paperwork still has to be completed, but skipping court greatly speeds up the process. 

One thing to be aware of is that a living trust only protects its contents. Assets that you did not transfer into the trust during your lifetime are still subject to probate. In order for the trust to function as intended, you must change the titles on your accounts and other assets. 

Choosing the Right Trust Based on Your Estate Goals 

There is no one-size-fits-all solution to choosing a trust because every situation is different. A testamentary trust is the best choice for an estate where you are more concerned with what will happen after your death than in your lifetime. Additionally, some people simply don't want to deal with the burden of funding a trust while they are still living. 

When you have property spread across multiple states, privacy is important, or your family situation is complex (think blended families, young children, or someone with special needs), a living trust is frequently the better option. Another reason to carefully consider a living trust is if your estate is large enough that court fees and delays would reduce what your family receives. 

In fact, estate planning can use both. The majority of the assets are managed and kept out of probate by a living trust. A testamentary trust in the will specifies how assets will be distributed to a particular individual or purpose. 

Common Misunderstandings About Testamentary vs. Living Trusts 

One belief some people have is that living trusts are only for the ultra-wealthy. This is not true. Anyone who owns property, values privacy, or wishes to spare their family the time and cost of probate can benefit from a revocable living trust. Establishing one is frequently less expensive than what probate would cost. 

The second misunderstanding is that managing testamentary trusts is simpler. Since there are no assets to retitle, they might be easier to set up while you're still alive. But the ongoing administration is a different matter. In many states, a testamentary trust stays under court supervision after probate, which adds layers of complexity and cost over time. Trustees may be required to file annual reports with the court, something most living trusts don't require.  

No trust eliminates the need for preparation and guidance. Both frameworks must be meticulously written and adhered to, which is why most people seek out an estate plan from professionals who understand a client's trust needs. The strategy behind the legal document is what makes all the difference. 

Why Professional Trust Administration Matters 

Regardless of the type of trust you select, the quality of trust administration has a significant impact on whether your wishes are correctly carried out and whether your beneficiaries are protected. Acting in the best interests of beneficiaries, maintaining accurate records, making wise investment decisions, managing taxes, and adhering to the terms of the trust instrument are just a few of the many duties that trustees have. As the trust expands or the beneficiary's circumstances alter over time, those obligations become more difficult. 

Relationship tension and conflicts of interest can arise when a family member is appointed trustee, particularly when discretionary payouts are involved. In addition to lowering the risk of personal liability for trustees, professional trust administration offers the unbiased, consistent oversight that complex trusts require. 

Working with an experienced institutional trustee increases accountability and credibility when overseeing a testamentary trust under court supervision.

Protecting Your Legacy With the Right Trust and Trustee 

Whether you prefer the post-death control of a testamentary trust vs. a living trust's privacy and avoidance of probate, the most important thing is to make a thoughtful decision based on your circumstances and then see to it that it is executed correctly. The foundation is the structure of trust. That foundation is maintained over time by the trustee and the administrative procedure. An estate plan becomes a lasting legacy when it is carefully planned and consistently managed.
