A practical guide to defensible disposition, digitisation, and secure destruction

Legacy records cleanup involves organising, classifying, and making informed decisions about an organisation's accumulated physical record inventory. This process is essential because failing to address legacy records can lead to increased storage costs and compliance risks, and will hinder access to valuable data locked in paper files.

Legacy records are physical documents and files that have accumulated over time, often lacking metadata, proper classification, or current organisational context. To clean up your entire records inventory, you need a variety of approaches to address various challenges. Thanks to advances in technology and innovative thinking, the time has finally come to put order to your paper records and legacy inventories.

There are many reasons why it's critical to address your organisation's physical legacy records:

• Reduce the cost of storage (organisations typically see 40-50% storage cost reductions after cleanup)
• Prevent over-retention and ensure compliance
• Provide timely access to needed records
• Utilise data locked within files
• Achieve your goal of zero unnecessary boxes or adopt paper-lite ways of working
• Make decisions on records to digitise to support AI

To be successful in any of these pursuits, you must start by making defensible decisions (legally supportable choices based on documented policies and procedures) about your records, by file or by the box.

But taking action and making defensible decisions is easier said than done. Over the years and even decades, organisations may have used different indexing systems or procedures for categorising boxes. They may have experienced reorganisations or perhaps been through a merger, acquisition, or divestiture. And, most likely, employees have come and gone over time, taking institutional knowledge and ownership of records with them.

All of these situations have compounded the problem and left you with a difficult puzzle that needs solving, and you probably don't have the time, budget, or people to sort out the pieces.

How to manage your legacy paper records

Managing legacy paper records starts with understanding what you have, where it is stored, and what decisions need to be made. The core steps are:

• Inventory your records. Identify and categorise your records based on the clean up need - keep, destroy, or digitise.
• Categorise your records. Assign missing record classification codes, identify unknown content in boxes, and organise your commingled files.
• Apply retention rules. Determine which records are eligible for destruction, which must be retained, and which are candidates for digitisation.
• Execute disposition decisions. Destroy, archive, or digitise based on retention status and value to the organisation.
• Document every decision. Maintain an auditable trail of every disposition action to support legal and compliance requirements.

The challenge is that most organisations lack the necessary visibility, technology tools as well as resources to complete these steps at scale.

The traditional approach

Lifting the lid of every box to manually review contents, update metadata, assign classification, or sort files isn't cost-effective or entirely defensible, which is why few organisations have taken action.

So what's different now?

Technology that standardises and automates the process enabling objective decisions about your inventory, regardless of its cleanup challenge. You can determine what to keep in paper format, digitise, or defensibly destroy, and you don't need to do it all by yourself.

But as previously mentioned, not all boxes are alike in their contents, descriptive information, or metadata. Here are three common scenarios that require different approaches to enable your defensible decision-making:

Scenario	Core Problem	Recommended Solution
Records without assigned records retention codes	Cannot initiate legal holds or make defensible disposition decisions	Iron Mountain Smart Assign: Automated records retention code assignment aligned to retention schedule
Commingled records	Mixed files with different retention dates prevent box-level disposition	Iron Mountain Smart Sort: File-level sorting into new boxes by destruction eligibility date, record type, or whatever is required
Boxes with little to no descriptive information	Unknown contents make retention and disposition decisions impossible	Iron Mountain Smart Reveal: Make informed decisions by reviewing photos captured of your inventory

Scenario 1: Is a traditional approach to legacy records cleanup efficient?

Traditional, manual methods for cleaning up legacy paper records are labor-intensive, inefficient, and reliant on highly skilled professionals. Furthermore, these manual workflows frequently produce subjective decisions that lack defensibility. At scale, the greatest challenge of a cleanup initiative is not the physical handling, but rather the considerable time spent examining, researching, and determining the appropriate disposition for each record.

Identifying an entry point presents another major obstacle. An organisation's inventory often involves varying cleanup requirements, making it difficult to match specific boxes with their corresponding solutions. Consequently, these complications can delay the overall progress of the cleanup journey or lead to its deprioritisation.

Scenario 2: How do you handle boxes with commingled record types?

You have boxes with commingled records and event-based retention rules (retention periods triggered by a specific event, such as contract termination or loan closure, rather than a fixed date). Different record types have different retention and disposition requirements. If files aren't organised according to record classification, retention requirements, or event date, you can't confidently and defensibly take action on what records to retain, digitise, or destroy.

For example, mortgages executed for May 2007 are in a box along with loans that were terminated in 2009, 2018, and 2023. It's impossible to assign a single destruction date to the box, so the result is over-retaining some files while waiting for others to meet retention requirements.

A manual approach would require knowledgeable staff or contracted professionals to lift the lid of each box, compare the information for each file with a database that logs closure, remove the files that are closed, calculate their destruction eligibility (based on your retention schedule), and then place them in a box based on the destruction year. Or you may opt to digitise some of the loans as requested by the business unit.

But if you lack the resources, staff, process, and time to sort each file by destruction date, a cleanup project like this could be put off, ultimately increasing your storage budget and exposing your organisation to potential legal and compliance risks.

Scenario 3: What can you do with boxes stored without sufficient information?

You have boxes with not enough usable or credible information with which to make a decision. These could be boxes full of important records that must be addressed or holiday decorations, desk supplies, and personal objects that no one has claimed.

You could opt to lift lids and allow staff or a third party to make a determination, but you need space and the process is time-consuming, expensive, and not foolproof. To properly manage your records inventory and make disposition decisions, you need to know what you have and who is the rightful owner of each box. Without knowing both, you can't take action and will hold on to your inventory for much longer than necessary.

To remedy this situation, you need to review the contents of each box and manually update the box-level metadata. But you may not have the budget, staff, expertise, time, or space needed to complete such an extensive project.

How to achieve defensible disposition for your records

Defensible disposition requires that every decision about a record can be legally supported through documented policies and procedures. To achieve it:

• Establish a formal organisational records retention schedule aligned to current legal and regulatory requirements.
• Apply consistent records retention codes across all boxed records before initiating any disposition activity.
• Sort and re-organise commingled files before attempting box-level disposition decisions.
• Document every disposition event in an effort to prove what action was taken, when it was taken and why it was taken.

Skipping any of these steps creates gaps that may not surface until a legal hold, audit, or litigation request exposes them.

Should you DIY or outsource your legacy records cleanup?

Many organisations attempt legacy records cleanup internally, only to find the project stalls due to lack of skilled staff, the most effective starting point or the lack of a cost effective solution. Here is how to assess the right approach:

DIY may work when:

• Your inventory is small, reasonably well-organised and discoverable
• Staff have the time, expertise, and physical space to review box contents
• Your retention schedule is current and clearly documented across record types
• You have a workflow which provides you with a defensible output

Outsourcing is the stronger choice when:

• Your inventory spans thousands of boxes and you’re unsure as to where to begin
• Staff turnover has created gaps in institutional knowledge and record ownership
• You need results on a defined timeline with documented defensibility
• You lack the physical space to conduct manual lid-lift reviews at scale
• You recently went through an acquisition or M&A, and merged records

For most organisations managing large legacy paper record inventories, partnering with a qualified records management provider and using automated classification tools delivers faster, more defensible results at lower overall cost than a manual in-house effort.
