Several documents are commonly used in estate plans:
A will is probably the first document that comes to mind, and it's the master plan for how your property and assets are going to be distributed.
Trusts are also found in estate plans, and they protect your assets while giving you control over who will receive them after your death. There are many kinds of trusts, and a California attorney can help you choose the right one.
Your estate plan may include power of attorney, which gives someone the legal right to decide on their behalf if they are incapacitated. You can have a power of attorney for healthcare and financial decisions.
If you have children, an estate plan will include plans for any children under 18 in the form of guardianship designations.
