Why do you want to do an adult adoption? In most cases, it's simply money down the drain.
As an adult, you can do whatever you want and spend time with anyone you want without being adopted. They can put you in their will. They can give you power of attorney for medical decisions.
The biggest thing that really changes is that it gives you some rights if they die without a will.
Of course, if you want to do it, it's not as difficult as doing it with kids when the other parent can object.
