A property inspection is not needed for any spousal visa application, whether the application is made outside the UK or inside the U.K
If the solicitor is recommending one, they are likely just trying to make some extra money off you as they get commission etc. If a solicitor says you need one, it’s a red flag that they don’t know what they are talking about and may not be the best person to assist you.
Unless you have serious criminal convictions or a history of refused visas or illegal working or overstaying in the U.K., you are unlikely to need a lawyer at all. All the information and advice about how to apply can be found for free on the UKVI website and here on the forum.
Edited to add:
- your Land Registry document is all you need, though you can also include your latest original mortgage statement if you like
