The Core Legal Rule: It Must Be Their Will
A will must express the wishes of the person making it, called the testator. If you write a will for someone else, it must be their words, their decisions, and their final approval. You cannot make decisions for them or put in what you think they want.
The law requires that the testator understands what a will is, what property they own, and who their natural heirs are. They must also be free from undue influence—meaning no one pressures them into changing their will. If you write a will and include yourself as a beneficiary, courts will be especially suspicious.
In most states, a will is only valid if the testator signs it, or directs someone else to sign in their presence, and if they are of sound mind. If you sign for them, you must do so at their direction, in their presence, and in the presence of witnesses. State rules vary on the exact formalities, so check local law.
- The testator must approve every word of the will.
- You cannot write a will for someone who lacks mental capacity.
- You cannot include yourself as a beneficiary if you wrote the will, unless you are also a spouse or close relative and the will is properly witnessed.
- You cannot write a will for someone based on what you think they would want—only on what they actually tell you.
When Writing a Will for Someone Else Is Legal
It is legal to help someone write their own will, as long as you are acting as their scribe or typist. You can write down exactly what they say, ask clarifying questions, and put their instructions into proper legal language. The key is that the final document reflects their choices, not yours.
For example, an adult child might help a parent who has mobility issues but full mental capacity. The parent dictates their wishes, the child types them up, and the parent signs in front of witnesses. This is generally allowed, but you must be careful not to add your own opinions or suggestions that change the outcome.
Some states have specific rules about who can prepare a will. A few states allow non-lawyers to draft wills for others as long as they do not charge a fee. Others prohibit anyone who is not a lawyer from preparing a will for someone else, even for free. State rules vary, so it is wise to check your state's laws or consult a lawyer.
- Acting as a scribe is legal if the testator is competent and directs you.
- You can type or write the will, but the testator must review and approve it.
- You cannot make substantive decisions about beneficiaries or property distribution.
- Never write a will for someone who is confused, pressured, or cannot communicate their wishes.
When It Is Not Legal: Undue Influence and Fraud
Writing a will for someone else becomes illegal when you exert undue influence or commit fraud. Undue influence occurs when you pressure, manipulate, or coerce the testator into making a will they would not otherwise make. This can include isolating them from family, threatening them, or using your position of trust to control their decisions.
Fraud happens when you deceive the testator about what the will says, or when you forge their signature. If you write a will that the testator does not understand, or if you switch a page after they sign, that is fraud. Courts will invalidate such wills and may impose criminal penalties.
Even if you have good intentions, writing a will that does not truly reflect the testator's wishes can lead to a will contest after death. The court may throw out the entire will, leaving the estate to pass under state intestacy laws, which may not match what the testator wanted.
- Undue influence invalidates a will and can lead to legal action against you.
- Forgery or deception is a crime and will nullify the will.
- If you are a caregiver or have a fiduciary relationship, be extra cautious—courts are vigilant about these situations.
- Even a well-meaning rewrite can be challenged if it deviates from the testator's stated wishes.
Alternatives: Helping Someone Create Their Own Will
If you want to help someone, the safest approach is to guide them to create their own will using a reputable template or online service. You can sit with them, help them gather information about their assets, and discuss their wishes, but they should be the one making the final decisions and, ideally, typing or writing the will themselves.
Many online will-making tools allow the testator to answer questions and generate a document. You can assist with the computer or with understanding the questions, but the testator should provide the answers. After the will is printed, the testator must sign it in front of witnesses, and possibly a notary, depending on state law.
If the person has a large estate, complex family dynamics, or owns a business, it is wise to consult an estate planning attorney. A lawyer can draft a will that meets all legal requirements and provide advice on trusts, taxes, and other issues. This is the most reliable way to ensure the will is valid and reflects the testator's true wishes.
- Use a state-specific will template or online service, and have the testator fill it out themselves.
- Help them list assets and decide on beneficiaries, but let them make the final calls.
- Ensure the will is signed and witnessed according to your state's rules.
- For complex estates, recommend a lawyer—it is worth the cost.
Special Situations: Living Wills and Powers of Attorney
A living will is not a will for property—it is a document that states your healthcare wishes if you cannot speak for yourself. You cannot write a living will for someone else unless you have a valid power of attorney that grants you authority to make healthcare decisions, and even then, you must follow their expressed wishes.
If someone becomes incapacitated without a living will, you might need to seek guardianship or conservatorship to make decisions for them. This is a court process that gives you legal authority, but it does not allow you to write a will for them. A will can only be made by a person with mental capacity.
A durable power of attorney allows you to manage someone's finances, but it does not give you the power to write a will for them. You cannot use a power of attorney to change their estate plan. If you need to create a will for someone who is incapacitated, you cannot—they must have capacity to make a will.
- Living wills and powers of attorney are separate from last wills and testaments.
- You cannot make a will for someone who is incapacitated, even with a power of attorney.
- Guardianship may allow you to manage affairs, but not to create a will.
- If a person becomes incapacitated without a will, the court decides who inherits under intestacy laws.
How to Avoid Legal Trouble When Helping
If you decide to help someone write their will, follow these practices to minimize legal risk. First, document everything. Write down the testator's instructions, and have them initial or sign a note confirming their wishes. This can protect you if someone later claims you changed the will.
Second, never suggest changes that benefit you or others. If the testator asks for your opinion, be neutral and remind them that it is their decision. Avoid discussing your own inheritance or what you think is fair.
Third, make sure the will is signed and witnessed correctly. Most states require two witnesses who are not beneficiaries. Some states also require a notary. Follow the exact formalities, or the will may be invalid. If you are unsure, have a lawyer review the final document before signing.
- Keep a written record of the testator's instructions and have them sign it.
- Stay neutral—do not offer opinions that could be seen as influence.
- Ensure proper signing and witnessing, and consider a notary if state law requires.
- If anything feels off, consult a lawyer before proceeding.
