Unmarried pregnancy can get a marriage certificate, which is the same process as the normal marriage certificate.
Both parties will prepare the original ID card and household register, and the two people will go to the place where the form is received. The staff will issue a form after checking that there is no error, which mainly fills in general information (including name, age, ID card number, household address, etc.).
When registering, the staff will ask some simple questions, and then give each person a statement for applying for marriage registration. After filling in, the staff will ask men and women to stand up and read the statement.
After the above steps are completed without error, the staff of the marriage registration authority will issue a marriage certificate.
