An online lawyer is still a solicitor or a conveyancer, they just advertise their conveyancing services online.
The most important thing is that the conveyancing firm you choose uses modern methods of communication wherever possible, simply because to use Royal Mail when you could use email for example is likely to cause delays and may even result in essential documents being lost. If something can only be sent by post, then your solicitor will naturally do this.
People often wonder whether they should be looking for a property solicitors near me rather than choosing an online solicitor that does conveyancing. The fact is that your conveyancing lawyer never has to visit your property in order to carry out your conveyancing legally, efficiently and correctly and it is in fact easier, less time-consuming and less expensive to check your ID and financial capability using electronic means rather than meeting face-to-face. They can be sent vital documents such as your Building Survey and your local authority property conveyancing search electronically.
In fact you'll often find that if you choose a 'conveyancer near me' for example, on your local high street, they might well be more expensive. After all, they have to pay high street rates among other costs and they'll most likely charge you 'on the clock' for their time if you have to visit them in person for ID checking etc.
So instead of searching for a conveyancer near me, it's more advisable to examine your online conveyancing quotes carefully and it's highly important to consider matters such as their positive reviews and to take on board personal recommendations.
