If you have a son, daughter, sister, brother or parent living alone for whom you are responsible, and they unfortunately become incapacitated or die, apart from the emotional and medical burdens, you may have significant legal and financial troubles. A little planning in advance for these contingencies will go a long way in making any such dire situation much easier to handle.
If they rent, then make sure they notify their landlord, in writing, that you have their permission to access the apartment. Also get a key to their apartment or home or at least know where you can get one (such as from a neighbor).
A power of attorney will allow you to handle their legal and financial affairs during any period of disability. However, a power of attorney automatically ceases on death. Once someone dies, only the executor under the will may handle legal and financial affairs and it may take months and sometimes years to become appointed executor by the Surrogate’s Court. A properly created and funded living trust, on the other hand, gives you immediate control of their affairs upon death.
