Many older people add an adult child to the title of their assets (especially their home), often to avoid probate. But this can create all kinds of problems. When you add a co-owner, you lose control. Jointly-owned assets are now exposed to the co-owner’s creditors, divorce proceedings and possible misuse of the assets and the co-owner must agree to all business transactions. There could be gift and/or income tax issues. And if you have more than one child but only name one to be co-owner with you, fluctuating values could cause your children to receive unbalanced/unintended inheritances.
