It may work in other countries Alfredo, but it will not actually add any value to the Uk system because the thing it changes isn't the problem.
In the UK the system of asking questions after a sale is agreed is seen as bad and a source of delay that needs fixing. The government think that if they cure this by creating a "pack" for buyers they will just read them through and say that's fine and move in a week. What will happen is that the pack will either be incomplete or raise issues that have to be looked into and no one will be any further forward, plus the seller will be paying for the whole thing up front. I think it could push costs up significantly once the initial blood bath is over between the pack providers and a few organisations dominate the market.
What the government don't understand is that it's the system of chain conveyancing with many related sales and purchases that cause the problem. It's cumbersome and because the whole thing goes at the speed of the slowest person, who often has either a problem or a wish to delay things to suit their own purposes people get very frustrated by it all. It's actually rare for the sort of information that the packs will contain to cause a serious delay at present.
This time of year is a good example of the trouble chains cause, some people are desperate to eat their turkey on a packing crate come what may and the rest want to leave it till the end of January. The rows that develop over dates can easily waste ten days with everyone getting increasingly shirty until someone finally gives in and camps out at their mums for a few weeks
They are also adding energy efficency certificates to the packs which is just plain dumb euro burocracy. They will cost time and money to prepare and any fool knows a victorian house is less energy efficient than a modern one. There is no evidence the public actually want to know this as part of the buying process and it just adds to the waste of time and paper involved
No systems perfect and i'm sure even the Scottish one has it's flaws. I'm curious about Scottish Lawyers and bridging loans. Do you mean Scottish banks make a fortune, presumably they lend the money not the lawyers.
