How your property will be distributed by your Will. Note that this does not include life insurance policies and those pass as spelled out in the policy paperwork and designations you make there.
You should only create your Will online if your wishes are simple. For instance, most married couples desire to leave everything to each other first, and when the spouse dies then to the children equally. Most single parents desire to leave everything to their children and name guardians; and for people without children, most desire to leave their estates to their spouse, significant other, relatives or friends.
The customized Wills on this site allow you to do this quickly and easily.
If your situation is more complex, creating a Will online may not be sufficient to meet your needs. For example, if you have significant assets, want to disinherit relatives, set up complicated trust provisions, have a child with a disability, or anticipate family conflict, or if you have estate planning questions in general, you should seek legal counsel.
