ExH has agreed we can double barrel DCs surname after I have reverted to my maiden name on divorce.
I have googled and was all set to go through the hassle of paying £35, getting a solicitor to witness a form plus getting someone who has know us for 10 years to witness and have a solicitor witness that too. All this is stated on the gov.uk website hence me assuming you had to do it this way.
After googling some more, it appears you don't need to do all of this and as long as you both agree, you can fill in the deed poll, both sign and get witnessed and write a letter stating that you consent to this change. Apparently you only have to go through the gov.uk hassle if you intend to officially register the change with the London Gazette in order to get copies on the future, should they be needed. I'm not bothered about this.
Can anyone advise if a straight forward deed poll, signed by myself and exH with 2 witnesses plus a letter signed by us both saying we consent to the change, will be sufficient?
When I reverted to my maiden name I used a deed poll and there was the odd institution that were trying to argue it wasn't official as it didn't have the seal (which was rubbish, it didn't need it).
