Hi Teena
If your partner is in an IVA, this in itself will not prevent him from getting a mortgage. The IVA will be recorded on his credit file and this will mean that his credit rating will be poor. However, there are many mortgage lenders who are willing to lend to people who have poor credit ratings.
The more important thing to note is that your partner MUST NOT take a mortgage or change a current mortgage without first discussing this with his IVA Supervisor (normally the IP who set up his IVA). Someone who is in an IVA must not take additional credit without the agreement of their Supervisor 1st. If your partner took credit without his Supervisor's knowledge, this may break his IVA agreement and cause it to fail.
Of course, if you are not in and IVA, you can take a mortgage at any time. However if you need your partner to be included, then this can only be done with the agreement of his Supervisor
All the Best
