The most important consideration for couples with children is the welfare of the family as a whole. Children should be put through as little upheaval as possible and may need to remain close to school and childcare facilities. Consider your own needs too, in relation to accessibility to work, maintaining contact with children and keeping in touch with family and friends. The other main consideration is affordability in terms of what your other assets are, what your respective incomes are and what alternative properties are likely to cost so we can work out what your viable options are. However, it will all depend on what your family and financial circumstances are, so it is vital that you get legal advice so that you can understand your particular situation.
