tenant injured, part of rent will be late

[Jane S.]

Due to injury the "wife" (unmarried couple) was out of work for 3 weeks. The "husband" just emailed me. Injury occurred 3 weeks ago but they didnt inform me about paying late. They write. "We will be depositing as much of our rent as we can on the first--2 days from now-- and will deposit the rest promptly on the 10th when her check hits our account ." Note, he has a good job and a "big" trust fund. If they had called me when it happened I could have worked something out. This way they are making the decision unilaterally (tenants with ownership complex). should I charge late fee for 9 days at $50 per day or make a deal? I have no idea what "as much of our rent as we can" means. They have not been late so far (moved in July 1 2019)
