Well Ritchie its nice to find a forum that is interested in what we are doing.
My Company Wincham Investments Ltd specialises in investing Spanish property owned by British Clients into UK Private Limited Companies.
Sounds complicated but it is not we and our Spanish Partners undertake all the work .and it is painless to the client at a modest cost.
There are many benefits of Corporate Property Ownership,the main one is that it eradicates Spanish IHT entirely and all the probating costs.
There is no treaty between the UK and Spain in respect of IHT as in Spain it is the recipient that has to probate and is taxed ,in the UK it is the estate that is taxed so double taxation applies

With the property Invested into a UK Company, no taxes in Spain this means No Probate in Spain ,No Frozen Bank Accounts ,No 12 mths waiting and No IHT ,there is no wealth tax and no 25% tax on income
In the UK Shares in a UK Private trading Company are Exempt from IHT .There are many more advantages Ask any Questions about this subject and I will Post Answers.
