Temporary guardianship

Nope. This is really not a fill in the blank matter. There are a host of ancillary issues that likely have to be dealt with from financial, legal, personal and other perspectives. I would be hurting not helping you. Get an attorney in your area specializing in estate planning and administration. You might also need the help of a CPA or financial planner too. If the cost is an issue speak to the Surrogate’s Court in your county (it might go by a different name), call the bar association to perhaps get a suggestion. Get help, this is unlikely to be a do-it-yourself project.
