There are some ways to give money to children that can result in difficult issues, as Kiplinger points out in "5 Ways NOT to Gift to Children ... and 5 Better Ideas."
Giving children a little money now, might go a long way to helping the child make a lot more money later. However, many parents are so eager to give to their children that they do not think through the best ways to make the gifts.
The most important thing to understand is how giving a child something might affect them and you in the future. For example, if you give a child a large sum of money outright and the child gets divorced, it is possible that your child’s future ex-spouse and not your child could get part of the money in a divorce settlement.
Other common mistakes include transferring a piece of real estate outright to a child, or naming a child as the joint owner on a piece of real estate. Both of those approaches are fraught with potential problems and could prove to be very disadvantageous for both the parent and the child.
The best thing to do is to be careful and talk to a qualified estate planning attorney before giving any assets to a child.
