What is the treatment of goodwill when we relocate our business?

no revaluation of godwill is done cuz it increase in value of goodwill will be because of company internal operation i.e that would be internally generated which according to IAS38 cant be recognised..which it will be chek out for impairment..

It should be revalued. Its value may increase or decrease, depends on the basis upon which it was calculated.
