Many people can draft their own wills with the help of a book or will-making software. Make sure you use the right laws for your state. However, you might consult an attorney if:

Your estate is large enough to be subject to estate tax. This number changes every year but is generally more than $2 million.

You want to leave any assets in trust for a spouse, children or other heirs. A trust lets you attach strings to the distribution of your assets. A so-called living trust lets you shield assets from probate.

You own a business and have questions about who will own the business after your death.

You are divorced and remarried, have stepchildren or other complex family relationships.

You are afraid someone will contest your will.

Even if you have simple circumstances, it's fine to have an attorney draft your will for peace of mind.
