I agree with the earlier answers concerning taxes. While I do not know your situation, I would also recommend that you open a separate account for these funds. Do not mix any other funds in the account. Use these funds as a last resort. Once you use any funds from the account, do not replenish the account. Try to keep track of where the funds are spent, particularly for larger expenditures such as homes, home improvements, vehicles. Consultation with a financial planner or non-profit financial counseling agency is also advised.
