I don't see where that's documented :
RAC: Frequently Asked Questions [ID 220970.1]
But it makes sense since I don't see how you would do it any other way without conflicts.
Going with Yes - Seems like they refer to it as "redo apply instance"

We are planning to create a 3-node RAC physical standby for our 3-node RAC Primary DB. I was told that the mrp process (Managed recovery process) at the standby site should be configured to run only on one of 3 instances in the standby side. Is this true ?
you can refer MAA article for RAC primary and RAC standby http://www.oracle.com/technetwork/database/features/availability/maa-wp-10g-racprimaryracphysicalsta-131940.pdf
primary : 3-node RAC and all 3 nodes can ship the archivelogs to standby site

Standby: 3-node RAC and only one of the instance will apply the recevied logs (i.e MRP runs on only one node at any point of time)
From what I have read since you posted the question, that would be correct.

yes, it will run form node3.
So, this means, during the last stage of Standby setup , whichever Instance I connect and issue alter database recover managed standby database disconnect from session; If I issued the above command from Instance 3 , the mrp process will be running only on Node3. Right ?
