DTAadvice

Not sure if is the right forum? I am a UK Citizen, UK Nonresident, Thailand Tax resident. Regarding a possible future sale of UK rented property. I understand about CGT as regards the UK. I am getting conflicting advice regarding the Thailand UK Double Tax Agreement, can you please confirm the meaning of Article 14, paragraph 1 of the DTA? "Capital gains from the alienation of immovable property, as defined in paragraph (2) of Article 7, may be taxed in the Contracting State in which such property is situated." I am told by a Tax Lawyer, who is a Director of a large company so a knowledgeable and reliable source that, the words "may be taxed" are not used in the usual Laymans terms, instead in this legal situation they mean that because the UK has CGT legislation it is only subject to CGT legislation in the UK and not subject to Thailand's tax laws. As I said I have read other conflicting articles and have spent hours trying to get the answer. Please confirm the intention of 14,1 of the DTA.
