Try this link; look into the Personal Bond form, download it. This works for Malaysia My Second Home program.
I do not believe that you need to deposit MR1500 for your husband's visa. You, as Malaysian Citizen, can sign the bond. Follow the instructions in the form. You will have to spend MR10 to buy a stamp from Revenue Department. That is all the expense you will have to incur.
In case there is a breach, the Malaysian Government will come after you for RM1500. That is how bond works. It is similar to insurance.
