We were never married. I had my older twins before we were together, we only have my youngest together. Where would one get this form and how would he put they don’t live with him permanently?
If you were never married, then he can't legally claim the twins as dependents unless they lived in his home the entire year.
To allow him to claim the biological child you share, you can download this form, print it, fill it out, sign it, and give it to him. This form says that although the child lived with you, your ex is allowed to claim the child for 2025. (You can make the form effective for one year at a time or for future years as well, I would probably stick to one year at a time.) He must mail the original signed form to the IRS after he e-files, he should keep a copy for his records.
