The rental property had a fire and I am managing all the repairs. However, the county believes my dad is not moving fast enough to make the repairs and asked he appear in court. Considering he has advanced dementia and has a Power of Attorney in place- me taking care of any financial issues. The court says I cannot represent him and that only a lawyer can talk on his behalf. We cannot afford to hire a lawyer. Is it true I cannot represent him in this case? I live in Michigan.
