Yes your father can contribute financially. The concern is that his financial contributions may be deemed as gifts and result in a period of ineligibility for long term care medical assistance if he eventually needs skilled nursing care in a facility. So his contributions should be done w/in the context of a written agreement. It's entirely appropriate for him to pay something for his room and board. You should consult with an Elder Law attorney to assist you with this process and to give you additional advice on how to preserve his assets and plan for the potential need for medical assistance.
I recommend that you seek out a local attorney for a more in depth discussion of the matter. I do not recommend that you take any action steps without such a consult. Act quickly because by waiting, you may lose certain rights and remedies available to you.
