Overview

Legal parenthood decides who, in law, is recognised as a child's parent, and it depends on the couple's relationship status, and whether donated gametes are used.

The person who gives birth is always the legal mother; whether a partner is also a legal parent depends on marital status and consent. This article sets out which forms apply in each situation and why marital status must always be confirmed before treatment.

Note: The law in other countries may differ from the UK. Nationals or residents of other countries, or patients treated with gametes from nationals or residents of other countries, should seek independent legal advice.

Prerequisites

  • The patient's confirmed relationship status: married, in a civil partnership, or neither.

  • The confirmed source of gametes: own or donor eggs and sperm.

  • Where donor gametes are used by an unmarried couple, the legal parenthood consents completed before treatment.

Instructions

Confirm marital status and gamete source first

  1. Confirm whether the couple is married, in a civil partnership, or neither.

  2. Confirm the source of the gametes (own or donor eggs and sperm).

Warning: Marital status is the factor that decides whether parenthood election forms are needed. If it is recorded incorrectly, the partner may not become the legal parent, or required forms may be missed, which can force the couple to go to court after the birth. Always verify the status against evidence before treatment.

Note: Verifying and evidencing marital status is covered in a separate article. [KBA: Checking and verifying marital status — to be linked]

Apply the legal parenthood rules

The birth mother is always the legal parent. Whether the partner is also a legal parent depends on the rules below.

SituationRelationship statusLegal parenthood of the partnerForms required
Own eggs and spermAnyBoth partners are legal parents by virtue of the treatmentTreatment and storage consents only
Donor sperm or donor embryosMarried / civil partnershipPartner is automatically the legal parent, unless they did not consent to treatmentTreatment and storage consents; no parenthood election forms
Donor sperm or donor embryosNot married / not in a civil partnershipPartner is not automatic; parenthood must be elected before treatmentWP (birth mother) and PP (partner), completed before insemination or embryo transfer
Single woman, UK-licensed donor spermSingleBirth mother is the sole legal parent; the donor has no legal rights or responsibilitiesNo parenthood election forms
SurrogacyAnyThe surrogate is the legal mother at birth; intended parents acquire legal parenthood after birthParental Order through the court after the birth, with the surrogate's consent

Note: The same WP and PP pair applies to female same-sex couples who are not married or in a civil partnership, including shared motherhood where one partner provides the eggs. The birth mother completes the WP form and the partner completes the PP form. In shared motherhood, the egg-providing partner also gives consent to her eggs being used in her partner's treatment.

Warning: WP and PP must be completed before the sperm is inseminated or the embryo is transferred. They cannot be completed after treatment. Errors or omissions can mean the partner is not recognised as the legal parent.

Understand the related forms

These forms support treatment but are separate from the legal parenthood election.

FormPurpose
WPBirth mother's consent to her partner being the legal parent (parenthood election)
PPPartner's consent to being the legal parent (parenthood election)
Women's / Men's consent to treatment and storageConsent to the use and storage of eggs, sperm, or embryos for treatment
WD / MDConsent to donating eggs / sperm
LCStating a spouse or civil partner's lack of consent, where a still-married couple has separated

Note: Either person can withdraw their parenthood consent in writing before treatment takes place, using the relevant HFEA withdrawal form. Consent to disclosure of information is a data-sharing consent and is not a legal parenthood form.

Check before treatment

  1. Confirm the correct forms for the couple's status and gamete source are completed and signed.
  2. Confirm parenthood forms are dated and completed before insemination or embryo transfer.
  3. Retain copies in the case record as inspection evidence.

Expected Outcome

The correct parenthood and treatment forms are completed for the couple's relationship status and gamete source, parenthood is validly established before treatment, and the case record holds the evidence required at an HFEA inspection.
