Your husband or partner has the right to take time off to attend up to two antenatal appointments, but the statutory right is to unpaid time off. This right is also available for intended parents in a surrogacy arrangement who qualify for and intend to apply for a Parental Order. If there is a recognised union in your workplace, there may be better rights in place (for example, a right to paid time off).
The time off is capped at six and a half hours per appointment.
The employer is not allowed to ask for evidence of the appointment. This is because the appointment card belongs to you, as the expectant mother. However, the employer can ask for a signed declaration stating the date and time of the appointment and confirming that your husband or partner is in a qualifying relationship with you or your expected child and that the purpose of the time off is to accompany you to the appointment, made on the advice of a GP or midwife.
