Form Overview
Form No.15 is a request to vary securities that have been deposited under the Trade Union Act 1941. Use it when a trade union wants to change the amount, type or terms of the security it has lodged with the courts.
Plain English
If your union has already put money or property on hold with the courts and now needs to adjust that deposit, you fill out this form. It tells the court what change you are asking for and why. The request is then considered by the court before any new security is accepted.
