Thanks for your question.
I'm afraid that her name cannot be removed from the registered title to the property without the lender's consent, they have a first legal charge which prevents this. They will require you to be able to demonstrate sufficient finance in order to receive a mortgage offer in your sole name.
If you are able to do so you can do a transfer of equity from your joint names to your sole name and remortgage in your favour. The repaymenst you would then make would depend on the mortgage offer you can negotiate and receive from your lender.
This would not in and of itself prevent your wife from revisiting financial settlement pursuant to divorce (incluing the equity in the house) at a later date)
Really though, if you are to only eventually divorce you should see a solicitor about this and ask them to draw up a separation agreement confirming the agreement you have reached with regard to the property and any other matters (eg. payment by non-resident parent to resident parent in respect of the child, child's residence).
Ideally you would wish to have a Court order made as to financial settlement during the divorce process but the SA above does afford a degree of security for you.
