Requirements for Spouse income whos a student abroad

Recently got married and about to apply OSAP for more funds

My spouse was in Canada for 2 year on visitor visa, mainly for church purposes and also typical visit. He received financial support from church and friends but no work was involved. Hes back in his home country now and taking univeristy back there. As im applying for osap, i have few questions.

1. Our marriage certificate isnt due yet for pickup until 6-8 weeks but OSAP requires that so I plan to wrtie an affidavit. thats the only option they give me. I dont how how much it even cost and how both of us will be able to sign it in front of a lawyer

2. theres 3 requuired documents OSAP is requesting me and im not sure how to go on about this
