You must also formally consent to your nomination in writing.1
The content of the consent to nomination form is fixed by law.
On the consent to nomination form you will be asked to state you not disqualified from standing.
You must also state your date of birth.
You are not allowed to sign the consent form earlier than one month before the deadline for submitting your nomination papers.
Your signature must be witnessed, and the witness must sign the form and give their full name. There are no restrictions on who can be a witness to the consent to nomination.
If you are abroad and the Constituency Returning Officer (CRO) is satisfied that because of your absence from the UK it is not practicable for you to give your consent in writing and deliver it by hand to the CRO, you will be allowed to provide the consent by fax or email, and will not require a witness to sign the form.
