If you want to stay in your home as long as possible, it is important to define how you want your home managed during your last years and after. If you don't, your heirs may end up in court litigating over what is to happen to the property. There may be issues over who they think is owed the inheritance or they may argue over whether it should be sold or kept in the family. It may even surprise you to learn that no one may want the house and would rather sell it as soon as possible. Either way, if you don't take care of it now, someone else will decide for you.
If you are not sure what you want to do with your home but do know you want to live in it as long as possible, you should contact an estate attorney. Your lawyer can help you figure out the best way to secure the future of your home, which may be by including it in a trust or a Will.
