UK listed shares held offshore in brokers account

In general, UK situs assets will be subject to IHT whether UK resident or not.

Where a non resident holds shares in a brokers nominee account outside of the UK will they be considered not UK situs as it is the broker that holds the shares as opposed to the individual.

It is always best to use an offshore company but many non residents oppose this due to the related costs.

It would be interesting to hear what peoples thoughts are.

Many thanks
