Dear groom42
DBNO is quite right in what he says, and I endorse all of it, but I just have a feeling that 30 minutes is not going to be enough , or anything like enough, to deal with a problem like yours. I am sure you will need advice sooner or later, it's just a question of the right time to seek it.
There is one thought that keeps on coming through my mind, and it goes something like this.
One of the Court's priorities has to be to try and make sure that both of you are adequately housed. Where there are children involved - as is the case here - what normally happens is that the child(ren) stay with the mother. In most cases this has the practical consequence that the wife will be given the right to right to stay in the
marital home until the child(ren) reach majority. At this stage a number of things can happen, but let's leave that to one side for the moment. This is a very potted summary of the
normal type of outcome, and inevitably there are exceptions.
But in your case, your daughter is 15, and, from what I can gather, a rather strong minded young lady. At this age children are old enough to express a view. The difficult question I want to raise with you is - if, purely for the sake of argument, you do split, do you think your daughter would have any strongly held views as to whether she preferred to stay with her mother, or her father ?
I mention this because the Courts always put the interests of the child(ren) first. In most cases this gives an advantage to the woman, which - speaking as a man here - can operate harshly. If you think your daughter might plump for her father, then I think you probably do need the advice now, but considerations of time may well force you to concentrate on this important preliminary issue, because it my view a great deal could depend on the answer.
