Under ICANN’s Transfer Policy ICANN's rules for moving gTLD domains between registrars and changing registrants. Full definition of Transfer Policy, as of October 2026:

A sale is a change of registrant A change of a domain's owner details, with confirmation steps. Full definition of change of registrant. Both parties confirm, and the registrar processes it within one day.
The registrar then blocks transfers to another registrar for 60 days, unless the seller opted out beforehand. If the buyer wants another registrar, the policy advises the seller to request that transfer before the change of registrant.
A registrar may refuse a transfer within 60 days of creation or of a previous transfer. A completed transfer adds one year, up to ten years in total.
There is no bulk transfer Moving many domains between registrars in one registry operation, with ICANN approval.

Risks: trademarks, renewals and illiquid names

By registering or renewing a name, the registrant states under the UDRP that, to its knowledge, the name infringes no one’s rights. WIPO panels expect domainer Someone who buys and holds domain names as an investment. Full definition of domainer making bulk or automated registrations to screen names against trademark databases; those who deliberately do not can be held responsible under “willful blindness”. A dictionary word alone guarantees no defence. During a UDRP case, and for 15 business days after it, the name cannot move to a new holder.

Buying a portfolio does not inherit the seller’s dates: panels look at when the current owner acquired each name, for single names and whole portfolios alike. Merely renewing a name already held is not treated as a new registration when panels assess bad faith.

Other risks are price rises and names that never sell while renewals keep costing. Tax and accounting treatment depends on the country and on whether names are held for resale or for use: that is a question for an adviser, as any specific case is for the registrar, the registry or a lawyer.
