In order to claim Statutory Maternity Pay (SMP) from their employer, a woman must provide proof of her pregnancy from a doctor or midwife. This is usually given on form MAT B1
The MAT B1 certificate:
- verifies the pregnancy
- confirms the date of the expected week of confinement (EWC)
- confirms the actual date of birth when completed after confinement
Doctors or registered midwives must issue form MAT B1 free of charge to their pregnant patients for whom they provide clinical care.
