When you get married, the arrangement of offering tea should be decided according to your relationship with your parents and the specific situation after your parents divorce. The following are several possible arrangements:

1. If both your parents attend your wedding, you can offer them tea separately or at the same ceremony.

If your parents still maintain a good relationship after divorce, you can provide them with tea alone and express their respect and gratitude at the same ceremony.

If the relationship between parents deteriorates after divorce, consider offering tea to only one of them and expressing gratitude and respect to the other in private.

If one of your parents remarries, you can consider offering tea only to the one who has not remarried, and express your gratitude and respect to the remarried one in private.

No matter how you arrange to offer tea, you should show your love and gratitude to your parents and show the warmth and happiness of your family at the wedding.
