different question: same answer
The basic rules are the same in Qatar as in UAE.
The difference is that the UAE, has a dont tell dont show policy.
In general, if your partner has a vaild visa to enter the UAE, and remain, then there is no problem, behind closed doors.
If NO residence visa, then only a visit visa then expect complications until the relationship can be regularised.
I have no idea if the UK, civil partnership documents actually could be considered suitable, but the UAE does think that a relationship should be between two persons of different genders.
There are many threads here, so suggest you surf a little.
Good luck.
