my question is: let us say one dc collapses in AD forest 1 and I have another forest AD2 where both have trust relationship<br />
<br />
can I seize fsmo roles from AD forest1 to AD forest2

They are independent of each other. The trust is between two segment and it is transitive. <br />
<br />
The FSMO are per forest. &nbsp;They do not control or manage any part of the other forest. <br />
