For RIPE in document RIPE 303 (Procedure for Becoming a Member of the RIPE NCC), which can be found at http://www.ripe.net/ripe/docs/internet-registries.html
For APNIC at http://www.apnic.net/member/membersteps.html
For ARIN at http://www.arin.net/membership/index.html
For LACNIC at http://lacnic.net/en/mem.html

Three steps need to be taken to establish a new LIR:
1. Establishing an item about a local IR in the local IR list in RIR database.
2. Familiarizing yourself with registration procedures.
3. Concluding a business agreement to ensure that RIR starts sending you invoices.
