All adults have the right to make medical decisions for themselves, provided they have mental capacity to do so at the time the decision must be made.
You will be deemed to have mental capacity if you understand the decision you are making, why you need to make that decision and the consequences of making that decision.
This means that in most situations you are the only person who can decide what medical procedures (eg surgeries, treatments and examinations) you wish to receive, including during your pregnancy and childbirth.
Healthcare decisions may be made on your behalf if you lose mental capacity. In these circumstances, the person who can make healthcare decisions on your behalf depends on your situation. If you have made a health and welfare lasting power of attorney (LPA) (or welfare power of attorney (WPA) in Scotland), your attorney can make decisions on your behalf. If you have not made an LPA or WPA, your medical team (eg doctor) can make decisions that are in your best interest on your behalf. In doing this, they should consider your wishes (eg those set out in your Birth Plan).
If you are worried about losing capacity during childbirth, it is a good idea to make an LPA or WPA. You may also consider making a Living will / advance directive outlining any medical treatment you wish to refuse in the event you lose capacity.
