if my daughter is 19, in college, living with her mom,, do I as her father lawfully have to still pay for child support until 21

Legally you are obligated to pay child support until the child turns 18, some previous child support order would also state 18 or when child graduates high school. However, your settlement agreement and/or final judgment might obligate you to pay child support until 21, you have to check on that. Best of Luck, Helena Y.
