divorce petition form d8

hello. just after a few answers. sorry if already been asked a hundred times..

started divorce petition and am assuming for question 1 where it asks for date of marriage xx was lawfully married to xx, that i put my Maiden Name?? and then for 1a i state my now married name? is this correct?

Also both myself and husband born and always lived in uk so for q3 do i put habitually or domiciled?

and lastly, we have 2 children, one born before marriage, the second after, do i state in q6 which reads "no other child, now living, has been born to the petitioner/respondent during the marriage except..." our second childs name?? Or do i just cross it out because have already stated both children in previous question about children of the family??

sorry if rambling, just want to get this right first time and finding guidance notes to not be very helpful.
thanks in advance

Normally you put your married name in at one, and leave 1a blank unless you have changed your name since the marriage.

Q3 you would either put domiciled or use both, but do use the exact wording from the guidance notes

Re: Children - you put both children in Q5 and delete 'Except' at the end of Q6 (Q6 would be if you had been separated for a while, and had had a child with anither man since the separation)
