How to add custom form to action hook in WordPress?

Question

I'm trying to add reCaptcha to custom forms ( two custom forms ), well the first thing i did was to install the recaptcha plugin, it works great on all the standard form on the website.

My two custom forms are register form very a like to the normal /register/ on Wordpress, Which is working the recaptcha on, but on the custom once not working.

What i want is to add this two custom forms somehow to the standard hook of WP like the register form so the plugin will recognize them as a default form.

Is this possible in any way?

First thing you have to do is finding out what the plugin defines as "standard forms" as you called it (via an action/filter hook? or jQuery?). Then customize your script accordingly.
