What is voluntary establishment of paternity?
In Ukraine, voluntary establishment of paternity is a legal process by which a man and a woman who are not married jointly submit an application to the Civil Status Registration Authority (ZAGS) to officially recognize the man as the child’s father. This procedure does not require a court decision.
What documents are required?
To successfully establish paternity, the following documents are required:
- Passports of both parents;
- Child’s birth certificate (if the child is already born);
- Medical certificate confirming the mother's pregnancy (if the application is submitted before the birth);
- Written consent from the guardianship and custody authority (if the mother is legally incapacitated, deceased, or her whereabouts are unknown).
How to submit the application and obtain the certificate?
- Preparing the Application – the parents jointly or separately prepare the paternity acknowledgment application.
- Submitting the Application – the application is submitted to the ZAGS at the place of residence of either parent.
- Application Review – the ZAGS reviews the documents and makes a decision regarding paternity establishment.
- Receiving the Certificate – once the decision is made, the certificate of paternity is issued.
Note: if one of the parents is unable to personally submit the application, they may authorize the other parent or a representative by issuing a notarized power of attorney.
