How to Write a Will: A Complete Legal Guide

Knowing how to write a will is one of the most important legal steps any adult can take, regardless of age, wealth, or family situation.

Without a will, state intestacy laws decide who inherits your property. Those laws may not reflect your wishes or your family’s actual needs.

Why You Need to Know How to Write a Will

A will names a guardian for your minor children. Without one, a court appoints someone who may not be your preferred choice.

Per FreeWill guide, over 60% of American adults do not have a current will, leaving their estates and families vulnerable to prolonged probate proceedings.

What a Will Can and Cannot Do

A will directs the distribution of your probate assets: bank accounts in your name only, personal property, real estate you own outright, and valuables.

A will cannot override beneficiary designations. Life insurance, 401(k), and joint accounts pass outside the will to named beneficiaries directly.

A will names an executor, the person responsible for filing the will with probate court, paying debts, and distributing remaining assets.

For minor children, a will lets you name a guardian and a financial trustee. These can be different people if you prefer different roles.

Step-by-Step: How to Write a Will

List your assets: bank accounts, real estate, vehicles, investments, valuable personal property, and any digital assets with monetary value
Choose your beneficiaries: name each person or organization clearly, with their legal name and relationship to you
Name an executor: choose a trustworthy adult who can navigate paperwork, communicate with banks, and manage probate court filings
Name a guardian: if you have minor children, name both a personal guardian and a separate financial trustee for their inheritance
Sign with witnesses: most states require two adult witnesses who are not beneficiaries to sign the will in your presence

Legal Requirements That Make a Will Valid

Requirements vary by state, but universally a will must be in writing, signed by the testator, and witnessed by two adults who are not beneficiaries.

Holographic wills (handwritten and signed by the testator) are valid in about half of US states without witnesses, but are more easily contested in court.

Notarizing a will is not required in most states but makes it self-proving, which speeds probate by eliminating the need to locate and depose witnesses.

Per MetLife guide, a properly signed will that meets state requirements beats dying intestate with no legal directions every time.

Common Will Writing Mistakes to Avoid

Failing to update the will after major life events: marriage, divorce, birth of a child, or death of a named beneficiary all require revisions
Using vague language: say ‘to my daughter Jane Smith’ not ‘to my children equally,’ which creates disputes if children have different mothers
Storing the will in a place no one can find: keep the original somewhere accessible and tell your executor exactly where it is
Forgetting digital assets: cryptocurrency, social media accounts, and online business assets need explicit directions in a digital assets addendum
Not naming contingent beneficiaries: if your primary beneficiary dies before you, your estate needs a backup recipient named in the document
