They're talking about timeshare.
What's the translation for deposit & forward?
Example sentences:

- If I sell my week to anybody else, that person is not able to become a member of the Vacation Club if it is not a family member and therefore is not able to deposit this week.

- The possibility to deposit or to forward a membership week from one year to another year is part of your membership with your exchange company.

Many thanks!
