I will try to assist you with this is the other expert has opted out.
There is no reason why this could not be dealt with by way of a general Power of Attorney which either gives the right to do specific things (a particular lease for example) or to do anything within the partnership.
Although legally there is no reason why be done, you may find some banks or building societies or lenders or solicitors or whoever is on the other side of the agreement will accept the Power of Attorney.it is unlikely that HMRC would accept a partner’s signature as an attorney for another partner.
Because of these very general nature of an overall power of attorney, what you might want to do is have specific power of attorney is in respect of matter requiring signature or agreement.
If you are granting a lease for example, the new tenant solicitor may say that a signature by way of power of attorney is not acceptable. So the answer to your question is that a Power of Attorney may work if it’s acceptable to whoever it is on the other side of the transaction.
Can I clarify anything for you?
