OK here is what will help you if you have nothing in joint names.
Any documentation proving that you have a long and lasting relationship. eg. - mobile-other phone bills demonstrating that you have rung each others numbers lots during the period you are claiming for (you should be able to get old bills off your providers) - letters from both sets of parents documenting your relationship and to include important events eg holidays together, family events attended. Photos are also helpful if they really prove a point. - letters from other people who have known you as a couple especially people of good standing in the community eg police, clergy, lawyer, employer. - have you been away together? If so, holiday booking forms airline ticket stubs visas stamped in both pbuttports etc will show you holidayed together and will help. - If you have both been living at your parents you should have post addressed to each of you separately at that address. While this does not prove a relationship, it does prove that you have lived together and may bolster your case when coupled with info above. - anything, I mean anything, in addition to these which could in any way be seen as evidence.
Also remember that DIMIA will want certified copies of all these documents, not originals and not photocopies.
