Fetch related property via c#

Can you give me an idea of the relationship between the object being changed and the property you want to read?  A screenshot showing it all would be awesome.

See image below where I tried to explain the properties

So for this document you want to return 839?

1. Load the object that property 1085 points to ("env.ObjVer.GetDirectReference(1085)").
2. Load the text for property 1115.

Something like:

[EventHandler(MFEventHandlerType.MFEventHandlerBeforeCheckInChanges)]
public void TrocaMetadado (EventHandlerEnvironment env)
{

    if (env.ObjVerEx.Class != 6 || env.ObjVerEx.State != 163) return;

    ObjVerEx ob = env.ObjVerEx;
    var otherObject = ob.GetDirectReference(1085);
    var value = otherObject.GetPropertyText(1115);
    
    var propMotivo = ob.GetProperty(1329);
    propMotivo.Value.Value = value;
    ob.SaveProperty(propMotivo);

}

    var propMotivo = ob.GetProperty(1329);
    propMotivo.Value.Value = value;
    ob.SaveProperty(propMotivo);

}

I should also highlight that your code (and the code I gave, as it was adapted from that) will cause the audit trail to break.  You may want to read this: Audit Trail and Scripting (fixing "(M-Files Server)" in the audit logs)

Ok, Thank u Craig!!
